SPECIFICATION forming part of Letters Patent No. 511,804, dated January2, 1894.

Application filed March 25, 1893. Seria-l No. 467,598. (Nomodel.)

5 certain new and useful Improvements in Sliding Doors; and I do herebydeclare the following lto be a full, clear, and exact description of the1nvention,such as will enable others skilled 1n the art to which itappertains to make and 1o use the same.

My invention relates to an improvement in sliding doors and moreparticularly to such as are used for parlors,-the object of theinvention being to produce simple and elhcient devices whereby tomaintain the door in a perpendicular position and prevent it frombinding.

A further object is to construct devices for hanging a sliding doorwhich shall be simple,

2o cheap to manufacture, easy to apply, durable,

noiseless and effectual, in every respect, in the performance of theirfunctions.

.Vith these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts ashereinafter set forth and pointed out in the claims.

In the accompanying drawings: Figure lis a face view of a door and doorframe having 3o my improvements applied thereto the door being open.Fig. 2 is a similar view taken from the opposite side showing the doorin its closed position. Fig. 3 is a detail view.

A represents the door frame, the rear portion of which is intended toenter the partition wall of a room, and to said frame, j ambs ,a aresecured, between which jambs, the door B is adapted to move. The loweredge of the door is preferably provided with agroove 4o b, into which anarm b', secured `to the frame A, projects. The bar A of the frameispreferably Vprovided with a groove c, in which pins c projecting fromthe upper edge of the door, are adapted to move. An elongated plate C 45 is located rearwardly from the 'jambs, about midway between the topand bottom thereof, and provided with arms C', which latter are securedat their free ends to one ofthejambs a, thus supporting the plate C inproper posi- The plate C is provided with an elongated horizontal slotd, in which a slide e is adapted to move. A pin e projects from theadapted to enter and move in avertical elonl gated slotf made in a platef2, secured to and projecting from the rear edge of the door. The arm orbar D from its sliding connection with the pin e, projects downwardlytoward the lower rear edge of the door, and at its lower end is providedwith alaterally projecting pin g adapted to enter and move inaverticalslot g in a plate g? secured to the rear edge of the door B at thebottom thereof. A plate 7L, is secured midway between the ends of therear edge of the door and projects rearwardly therefrom. To one end ofthe plate h, a rod or ptman h is pivotally connected, the other end ofsaid pitman being pivotally connected to the arm or bar I),ata pointbetween its ends. A rod or pitman h2 is pivotally connected to the otherend 4of the plate hand the lowerend of said rod orpitman h2 is pivotallyconnected to the bar or arm D', at a point between the ends of thelatter.

In order to insure the easy working of the parts, I prefer to use brasswashers, between all the jointed connections.

I have shown the pitmen 7L and 71.2 pivotally connected to the arms orbars D, D at or near the centers of the latter or at distances from thefulcrums of said arms approximately equal to the lengths of thel pitmenas being the most convenient to effect the proper operation of theparts, but for different sized doors it is obvious that the size andlength of parts might be varied so long as proper relative proportionsare main tained. i

The devices above described are very sirnple in construction, cheap tomanufacture, easy to apply, durable, noiseless, and effectual inmaintaining the door in a perpendicular position and preventing the samefrom binding.

Various slight changes might be made in the details of construction ofmy invention without departing from the spirit thereof or limiting itsscope, and hence I do not wish to restrict vmyself, to the precisedetails of construction herein set forth, but, f

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent,isl. The combination with a sliding door, of ahorizontal guide supported by the door jamb, a slide adapted to operatein connection with the horizontal guide, arms or bars having looseconnection with the slide and v sliding connection with the door, androds or pitmen extending from the door to the arms or bars,substantially as set forth.n

2. The combination with a sliding door, of a plate having a horizontalelongated slot, supported by the door jamb, between' the top and bottomthereof, a slide adapted to operate in said elongated slot, arms or barshaving a loose connection at one end with said slide and at their otherends with'the rear edge of the door in proximity to the 'top and bottomthereof, and rods or pitmen connected to Said bars or arms at pointsbetweenthe ends of the latter, said rods or pitmen being pivotallyconnected at their otherends to the rear edge of the door in proximityto the center thereof, substantially as set forth] 3. The combinationwith a door jamb, and

door,said jamb and door each provided with elongated guides, of arms orbars having pivoted connection with the door jamb and sliding connectionwith the elongated gn'ides, and rods or pitrnen extending from the armsor bars to the door and pivotally connected with each, substantially asset forth.

l. The combination with a sliding door, of a plate having a horizontalelongated slot supported by the door jamb, plates having 'verticalelongated slots, secured to the rear edge of the door at the top andbottom thereof, arms or bars having laterally projecting pins at theirfree ends adapted to enter said verticalslots, a slide adapted tooperate in the horizontal elongated slot, a pin projecting from saidslide, said arms or bars having elongated slots to receive said pin, aplate adapted to be secured to the rear edge of the door centrallybetween the top and bottom thereof, and rods or pitmen pivotallyconnected to the ends of said plate and pivotally connected to said armsor bars at points between the ends of the latter, substantially as setforth.

In testimony whereof I have signed this y.specification in the presenceof two subscribing witnesses.

JOHN C. SCHMOHL.
